[win-pv-devel] [PATCH 0/3] Support discard/trim/unmap

[Owen Smith <owen.smith@xxxxxxxxxx>]

Add an upper filter to intercept discard/trim/unmap operations, translate to
SCSIOP_UNMAP commands and pass through storport to xenvbd. Xenvbd will then 
issue the correct BLKIF_OP_DISCARD operation to the backend (if supported).

Owen Smith (3):
  Prepare SCSIOP_UNMAP correctly
  Run XenVbd SDV after XenCrsh SDV
  Add XenDisk device upper filter.
